PATENT OFFICE This invention relates to a windowconstruction andinvolves certain improvements over the construction disclosed in myprior Patent No. 1,893,763, dated January 10, 1933.

to provide a construction similar to that of my prior patent but inwhich the side rails of the lower or inner sash andthe front or innerbead of the window frame are provided with cooperating inclined surfaceswhich serve to maintain a tight joint betweenthe bead andiframeregardless of the shrinking or swelling of the-parts and whichalso prevent lateral movementand rattling of the sashin the frame.

A further object is to provide an arrangement similar to that of myprior patent in which a storm sash or extra sash can be inserted in theframe below the outer sash, such storm sash being removable andreplaceable from the inside of the window and being so constructed thatit can be arranged in an inclined position to form a ventilator for thewindow.

A still further object is to provide improved means for holding thefront or inner beads on the window frame and which permit the beads tobe easily and quickly detached therefrom to permit the lower sash andthe storm sash to be removed inwardly from thewindow frame.

These and other. objects are attainedby the specific embodiment of myimproved construction illustrated in the accompanying drawings anddescribed in the following specification.

In said drawings: i

inwardly in position to form a ventilator, this view also showing indotted lines the position of the inner sash when detached from the frameand drawn inwardly;

Figure 5 is a transverse section on the line X-X of Figure 1;

Figure 6 is a transverse section on the line YY of Figure 1;

Figure '7 is a perspective view partly broken away showing theconstruction of the movable strips arranged in the window frame, one oneach side of the outer window sash;

Figure 8 is a fragmentary perspective view of the upper end of the frontor inner bead which I employ; and a Figure 9 is a section on the line 99of Figure 3.

Referring in detail to the various features of .One of the objects ofthe present invention is my construction, the window frame comprisesvertical side members H] which may be formed of plain strips. or boardsof uniform thickness.

A sill H is secured between the lower ends of the side members, In and atop member I2 is secured to the, upper ends of said side members. Afacing or finishing strip [3 is secured to the inner edge of the sidemembers l0 and similar strips l4 may be secured to the rear edges ofsuch members. i

Adjacent the rear: edge of reach of the frame members It] and suitablysecured to the inner face thereof is a rear head it, these beadsextending from the top to the bottom of the window frame.

The outer or upper sash of the window is arranged in front of the beadsI5, and this sash includes side "rails [6, an upper rail I1 and a: lowerrail l8. Betweeneach of the side rails I6 of the upper sash andtheadjacent side members In of the window framegIarrange a strip 20. Thesestrips extend-from the; bottom to the top of the frame and'as. they areheld in position by the upper andlower: sashes, it is unnecessary toattach the same -to:the window frame as such strips are intended to befree to move laterally against the rear beads 15. If desired, the strips20 may be loosely secured to the window frame by means of .a-slot andscrew connection such as illustrated in my prior patent, whicharrangementpermits limited lateral movement of said strips. As abovenoted, the upper sash is arranged between the strips 26 on oppositesidesof the frame.

The lower or inner sash of the window includes side rails 2!, an, upperrail22, and a lower rail 23. i The side rails 2| of the inner or lowersash are arranged to abut against the strips 2&3 heretofore described.:In other words, the inner or lower sash is Wider than the outer orupper sash to the, extent; of the thickness of the strips 29.

One of the features of my present improvements involves theuse-of astorm sash positioned belowthe upper sash andoutwardly of .the lowersash. This storm sash includes a top rail 25, a bottom railv2li and siderails 25, which side rails abut-against the rear beads l5 of the frame.The storm sashlike the upper sash is positioned between the side strips2!] heretofore described. To maintain the storm sash in position whenthe innersash is in its lowermost position, a lug or projection 21 issecured to each side rail 24 and these lugs or. projections are adaptedto contact with the side rails 21 of the lower sash. By thisconstruction; when the lower sash is pressed rearwardly aslaterdescribed, the storm sash as well asthe'side strips 2!]- andtheupper sash of the window will be forced rearwardly against the rearbeads I5. The meeting rails l8 and 22 of the upper and lower sash are soshaped and notched as to provide a tight joint and the same is true ofthe meeting rails i8 and 25 of the upper sash and storm sash. The jointbetween the lower rail of the upper sash and the upper rail of the stormsash is such as to permit the storm sash to be tilted forwardly when theinner sash is raised or removed as shown in Figure 4 of the drawings.

The inner edge of each of the strips 20 is provided with a bead 20awhich extends substantially from the top of the strip to the lower railI8 of the outer sash and this sash is arranged to slide between saidbeads 20a and the rear beads Hi.

The upper ends of the strips 20 form tongues 28b which are adapted to beinserted behind a transverse head 28 on the frame, which bead acts as astop to limit the forward movement of the strips 26.

As previously noted, an important feature of my improved constructionlies in the front head 30 and in its combination with other features.This bead is made up of a front or relatively fixed part 30a which isadapted to be rigidly secured to the frame members It] and a rear part30b slidably supported in a rabbet in the under surface of I the frontpart 30a, preferably by means of a series of pins 390 passing throughthe part 3012 and into the part 30a. Arranged between the parts 30a and3012 are several flat springs 30d which tend to force the part 301)rearwardly, or against the side rails of the inner sash when the beadsand the sash are in position in the window frame.

It will be noted that the springs 30d are somewhat wider than the parts30b so that the inner edges of said springs project into a longitudinalgroove 30c formed in the part 30a and extending laterally of the rabbetin the part 30a of the bead. This arrangement forms a shoulder to engagethe springs by which means the outward movement of the part 30b islimited. The springs 30d and the pins 300 thus serve to hold the partsof the beads 39 in assembled relation when they are removed from thewindow frame.

The outer edge of the parts 301) of each head 3% is beveled or inclinedas shown at 30 and the r side rails 2| of the inner sash arecorrespondingly beveled on their inner corners adjacent the window frameas shown at 2 la. The springs 30d normally force the parts 30b towardthe rails 2| and the surfaces 30) thus fit against and cooperate withthe beveled surfaces 2la on the rails. By reason of the cooperatingbeveled surfaces 30] and 2m it will be seen that the inner sash will befirmly but yieldably held against lateral movement in the window frameso that rattling of the window sash is prevented, but at the same time aclose fit between the bead and the sash is maintained at all timesregardless of the shrinking or swelling of the sash, and all danger ofthe sticking of the sash in the frame is obviated.

To hold the beads 30 in position at their upper ends, each is cut awayto provide an inclined portion and a tongue which cooperate with atransverse bead 32 as fully described in my prior patent. In additioneach bead 30 on its inner surface is provided with one or more inclinedlugs or pins 33 which engage correspondingly inclined holes in the sidemembers I ll of the frame. These pins 33 are inclined inwardly or awayfrom the lower sash so that they act in the nature of hooks to securethe beads in place. The outwardly inclined surfaces 30f on the beadscombined with against the beads 30.

the inwardly inclined pins 33 produce a wedge ef feet on the beads sothat they are firmly held in place against accidental displacementespecially when the inner sash is down. By raising this sash the beadscan be easily sprung or forced inwardly a sufficient extent to detachthem from the frame when secured.

. It is sometimes desirable to use the storm sash as a ventilator forthe window. This can be done with my improved construction. When theinner sash of the window is raised, the upper end of the storm sash canbe tilted inwardly to the position shown in Figure 4, in which positionit rests To permit such inward tilting, the upper portion of each siderail 24 of the storm sash is cut away as indicated at 34, the bottom ofsaid cut away portions being inclined so as to rest against the outeredges of the beads 30 when the storm sash is thus tilted inwardly. Thebeads 30 thus serve to hold the storm sash in position to act as aventilator. When complete removal of the storm sash is desired, one orboth of the beads 30 are removed and the sash can then be withdrawninwardly.

From the foregoing the construction and operation of my improvedstructure will be apparent and changes may, of course, be made in thedetails thereof. For example, a screen sash formed like the storm sashmay be used and either metal or wood may be employed in my construction.

Having thus described the invention, what is claimed as new and desiredto be secured by Letters Patent is:

' 1. A window construction comprising, in combination, a window frame,an upper or outer sash in said frame, an inner or lower sash verticallymovable in said frame, and a storm sash arranged in said frame belowsaid upper sash and outside of said inner sash, and cooperating means onsaid storm sash and said inner sash for holding said storm sash inposition when the inner sash is down.

2. A window construction comprising, in combination,a window frame, anupper or outer sash in said frame, an inner or lower sash verticallymovable in said frame, a storm sash arranged in said frame below saidupper sash and rearwardly of said inner sash, and cooperating means onsaid lower sash and said storm sash for holding the latter in positionwhen the lower sash is down, said storm sash being free to tilt inwardlywhen the inner sash is raised.

3. A construction as specified in claim 2 having means on said frame foryieldingly pressing said lower sash toward said storm sash.

4. A window construction comprising, in combination, a window frame, anupper or outer sash in said frame, an inner or lower sash verticallymovable in said frame, a. bead secured to said frame on each side ofsaid lower sash and inwardly thereof, for holding the same in position,a storm sash arranged in said frame below said upper sash and rearwardlyof said lower sash, said storm sash being tiltable inwardly when saidinner sash is raised, said storm sash having the side rails thereof cutaway to provide shoulders for resting against said heads when the sameis tilted inwardly, whereby the storm sash is held in an inclinedposition to form a ventilator for the window.
